Vortex flowmeter measurement techniques and application instructions

In order to obtain accurate power measurement data, the vortex flowmeter must have accurate and non-disordered power measuring instruments. The state of practice of the joint venture, according to the power meter (such as: vortex flowmeter) corresponding to the request equipment of the "Energy-using Units for Measuring Equipment and Management General", and at the same time enhance the management of the power measuring instruments, and set up a special person to supervise, Manage the use, protection and verification of each part of the measuring instruments to ensure the accuracy and non-disorder of the measuring instruments. The Information Management Department will use various parts of the power measurement instruments according to the practice, establish corresponding resumes and accounts, and use the Access software of the advanced ancestors to create a measurement instrument management system, and output all the materials of the power measurement instruments. The system actively grasps and manages the operation status of various types of appliances. The material details the entire skill material of the measuring instrument from activation to scrapping, and affirms the focus of daily management tasks according to its skill level.
Nearly 1000 pieces of measuring instruments controlled by the system, the system can intuitively display the operating status and calibration status of each piece of equipment, so as to verify the true condition according to the verification cycle in part, and according to the "Measuring Method" Requests are made once a year to develop a periodic verification measure.
In the past two years, the China Instrument and Control Society has conducted a special investigation on the development of China's scientific instrument industry. The consequences show that in 2010, China's scientific instruments exports 15.73 billion US dollars, an increase of 35.23%; exports 6.431 billion US dollars, an increase of 28.28%, the import and export deficit reached 9.39 billion US dollars.
Wu Youhua, vice chairman and secretary general of the China Instrument and Control Society, informed the Science and Technology Daily reporter that the domestic market occupancy rate of domestically produced instruments has improved, but advanced instruments still rely on exports. For example, the scientific instruments of China's universities, research institutions, national key laboratories, national level analysis and testing equipment, etc., are mostly export products; scientific instruments used by large and medium-sized enterprises such as steel, petroleum and electric power in unfavorable mission environments. The same is true.
Another phenomenon worthy of attention is that most of the scientific instrument companies in China have a relatively short time to establish, and small enterprises account for the vast majority. The R&D investment of enterprises can be weak, and the products are crowded into most types. In order to live in the market, in the strong market competition, enterprises compete to lower prices, increase profit margins, and also reduce the ability of R&D investment.
